LIFTING-JACK.

SPECIFICATION forming part of Letters Patent No. 250,497, dated December6, 1881.

Application led May 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE OASERES, of Freestone, county of Sonoma,State of Galifornia, have invented an Improved Lifting'- Jack; and Ihereby declare the following to be a full, clear, and exact descriptionthereof.

My invention relates to the class of liftingjacks, and more especiallyto certain improvements in those lifting-jacks which are used to liftthe axles of wagons, Src., to permit convenient access to the parts; andit consists in such a construction as will render it readily adjustable,dispensing with some of the usual bolts, nuts, and guides, and generallysimplifying the whole device,wherebyit is rendered cheap and yetefficient.

Referring to the accompanying drawings, Figure l is a view of mylifting-jack. Fig. 2 is a view of the bent arm.

Let A represent an appropriate base, to which is rmly secured thestandard B, bifurcated or slotted at its lower end, as shown at a, andprovided with a loop or guide, b, at its top.

O represents the sliding bar passing down through the guides b, andhaving above ashoulder or offset, c, with .an extension, D, providedwith a plate, E, on its top. Its lower end has the series of holes orslots d, as shown.

F is a side support, formed with or attached to the standard B. To thissupport, between its upper end and the said standard, is pivoted theoperating-lever G, one end of which extends outwardly, and its shorterarm or end curves upward, as shown. To this curved end is pivoted thelink H, which curves around,

'as shown,and has its lower end turned atright angles, and fittingthrough the slot a in the standard B, and is turned upward to form ahook, @,which tits through the holes l in the sliding bar O. This bentarrn of the curved link H, ttin g through the standard B, serves as atraveling guide for the lower part of the sliding bar C, and thusdispenses with any other devices for guiding said bar. By reason of itshook e it holds fast the sliding bar, and thus no bolts or nuts areneeded to secure the link to the sliding bar. It can be readily adjustedby removing the hook c from one hole (l and placing it in another, andby this construction renders it easy of operation and capable of beingquickly set. The lever G is so pivoted to the standard B that its shortarm, when elevated to its extent, will carryits point with its link Hpast the center, and thus lock itself. The weight may rest either uponthe shoulder or offset c or upon the plate E.

I am aware that curved links operated by a lever, and sliding in guidesupon a standard, and adapted to lock themselves, are not new. I do nottherefore claim such, broadly, my invention consisting merely in theconstruction whereby the device is simplified and made economical;wherefore- What I do claim as new, and desire to secure by LettersPatent, is-

'Ihe standard B,having a bifurcated or slotted lower end, a,and topguide, b, the sliding bar C, with its shoulder 0 and top plate, E, andhaving in its lower end a series of holes or slots, d, the curvedoperating-lever G, and the curved link H, having itsl end turned at anangle, passing through the slot a, and provided with a hook, e, adaptedto engage with the holes d iu the sliding bar C, the whole forming alifting-jack, substantially as herein described.

In witness whereof I have hereunto set my hand.

GEORGE OASERES.
